Web Content Update Notification via Hyperlink Color Coding Scheme

Publishing Venue

Abstract

Often times, web users visit sites that contain several embedded hyperlinks. The current way that the user checks to see if the web content on the other side of those links has changed is by following each of those links and checking one by one. This can be tedious and time consuming. Described herein is a methodology for notifying the user of updated web content automatically in a way that is unobtrusive and intuitive.

Web Content Update Notification via Hyperlink Color Coding Scheme

A web browser that would implement this methodology basically attempts to perform HTTP conditional GET commands on any links on the current page that the browser finds in its "history" (i.e. pages that the user has visited previously). The web server will only return content if the pages have changed since the last time visited. If content is returned by the web server, the browser can cache this data and inform the user that new content is available by changing the color of the corresponding hyperlink on the current page. As an added feature, the user can specify which sites he/she wishes to receive update notification on through any browser implemented mechanism.

If a user visits a page that they wish to receive update notification on, the browser already parses the hyperlinks and changes their color depending on whether or not they have already been visited.

If the server responds with a page, the corresponding link will change to some alternate color, flash or otherwise unobtrusively and visually cue the user that the link is associated with new content. The page returned from the server would then be cached by the web browser so that not only would the user b...
